I have been reading about exchanging sites. all of them have people who lost their money due to hacks, or investors got their accounts closed, frozen (Coindesk) without proper explanations, usually exchange sites let them deposit money, but they don't let them withdraw their money.
Kraken(some review sites list this is as one of the best exchange site, what a joke) is also a shit hole, the same thing, money and coins missing, buggy laggy website, no customer support.
How do you make money of cryptocurrency when the exchange sites are predators to hunt people's money? Decentralized trade sites maybe? If I read positive reviews about these centralized exchange sites , they doesn't seem genuine at all, most of the time, it looks like someone ordered them from Fiverr. Binance, Bitfinex with the Tether fiasco, Coinmama.... All of them looks like scummy attempt to get your money.
Its quite risky to invest in cryptocurrencies due to the fact that cryptocurrencies are not regulated by any central authority; for that matter it is very easy to loose your investment especially when you don't take much care of your private keys. However, if your accounts and transactions are managed with maximum care; then you can earn through trading, mining, participating in bounties and investment
